Product Overview: The NU 417 Cylindrical Roller Bearing
The NU 417 is a high-capacity single-row cylindrical roller bearing designed for demanding industrial applications. With principal dimensions of 85mm bore diameter, 210mm outer diameter, and 52mm thickness, this bearing is a key component in our NU 400 Series. As part of the broader Cylindrical Roller Bearings family, the NU 417 features a unique design with two integral flanges on the outer ring and a flangeless inner ring. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it ideal for non-locating bearing positions and applications subject to thermal expansion.
Engineered for high radial load capacity and high-speed operation, the NU 417's separable design simplifies mounting and dismounting procedures, which is particularly advantageous for machinery requiring frequent maintenance. Its robust construction ensures reliability and longevity in harsh operating environments.
Key Features of the NU 417 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent support for heavy radial loads.
- Axial Displacement Accommodation: The NU design allows for free axial movement of the shaft relative to the housing, compensating for thermal expansion and mounting errors.
- Separable Design: The inner ring can be mounted separately from the outer ring and roller assembly, simplifying installation and inspection.
- High-Speed Capability: Optimized internal geometry reduces friction and heat generation, enabling reliable performance at high rotational speeds.
- Robust Construction: Manufactured from high-quality bearing steel for superior durability, wear resistance, and long service life.
- Interchangeable Components: The separable components are often interchangeable with those from bearings of the same size and series, offering maintenance flexibility.
Common Applications of NU 417 Bearings
- Industrial Gearboxes: Used as non-locating bearings on gear shafts to support heavy radial loads and allow for thermal expansion.
- Large Electric Motors: Provides robust support for motor shafts, ensuring smooth and efficient operation under significant loads.
- Pumps and Compressors: Essential for supporting rotating assemblies in heavy-duty industrial pumps and compressors.
- Construction and Mining Equipment: Ideal for use in machinery like excavators, conveyors, and crushers where high radial forces are common.
- Rolling Mills: Supports the rollers in steel and metal processing plants, withstanding extreme loads and temperatures.
- Wind Turbines: Utilized in gearbox and main shaft applications to handle the significant radial forces generated during operation.
- Vibrating Screens and Shakers: The bearing's ability to handle heavy loads and vibration makes it suitable for material handling and processing equipment.
Benefits of Using the NU 417 Bearing
- Enhanced Machine Reliability: By effectively managing high radial loads and accommodating axial shaft movement, the bearing reduces stress on other machine components.
- Extended Service Life: The durable construction and low-friction design minimize wear and tear, leading to a longer operational lifespan.
- Simplified Maintenance: The separable design makes installation, removal, and inspection processes quicker and more straightforward, reducing downtime.
- Improved Operational Efficiency: Its ability to operate at high speeds with minimal friction contributes to energy savings and smoother machinery performance.
- Design Flexibility: The axial displacement capability allows for more tolerance in machine design and assembly, especially where shaft lengths are long or thermal changes are significant.
- Cost-Effective Solution: Its long life and low maintenance requirements result in a lower total cost of ownership for the machinery it's installed in.
